Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterChimney Cleaning in SeaTac, WA
A Level 2 chimney inspection and cleaning in SeaTac typically runs $280-$380 for a standard masonry fireplace with camera documentation included, and most appointments are scheduled within a week during peak burning season. SeaTac’s aging 1950s-1970s housing stock and unique airport-corridor vibration patterns mean cap displacement and crown cracking show up more frequently here than in neighboring cities. We dispatch crews from our Seattle office to serve SeaTac directly, and every job starts with a written price before any work begins. Call (425) 642-3485 for a free estimate.
Why SeaTac Homes Are Different
SeaTac’s residential streets were built primarily in the 1950s through 1970s to house Sea-Tac Airport and Boeing workers, and those original single-wythe brick masonry fireplaces with clay tile flue liners are now 50-70 years old. Many have never been professionally inspected despite multiple ownership changes since the city’s incorporation in 1990.
The marine climate at Sea-Tac Airport’s official weather station records roughly 38 inches of annual rainfall with persistent overcast and humidity that erodes mortar, fuels moss and efflorescence on chimney exteriors, and promotes heavy creosote condensation from the low-intensity fires typical of mild Pacific Northwest winters. Chimneys without functioning caps deteriorate markedly faster here than in drier inland markets.
Most distinctively, homes directly west of International Boulevard sit under one of the busiest international airport flight corridors in the Pacific Northwest. Decades of low-frequency vibration from heavy commercial and cargo aircraft on final approach accelerate mortar joint cracking and crown displacement at rates not seen in neighboring Burien or Des Moines, which lie outside the primary flight path. Our technicians routinely find chimney caps shifted or cracked on otherwise well-maintained homes in this corridor.
Our Main SeaTac Services
SeaTac homeowners most often call us for these three services:
Chimney Cleaning & Sweep in SeaTac
We perform NFPA 211 Level 2 inspections with camera-down-the-flue documentation on every SeaTac visit, removing Class I through III creosote deposits and checking for liner degradation common in 50-70 year old clay tile. The persistent marine humidity here means creosote condenses more heavily than in drier climates, and low-intensity fires don’t burn it off. Chimney Cleaning & Sweep in SeaTac.
Chimney Repair in SeaTac
Our SeaTac repair work focuses on mortar joint repointing, crown reconstruction, and spalling brick replacement in masonry chimneys subjected to decades of Puget Sound moisture and airport-corridor vibration. We document every defect with photos before quoting repair scope in writing. Chimney Repair in SeaTac.

AfterChimney Cap & Crown in SeaTac
SeaTac’s 50-70 year old masonry chimneys, compounded by decades of low-frequency aircraft vibration along the International Boulevard corridor, suffer cap displacement and crown cracking at unusually high rates. A properly fitted cap and intact crown are the primary defense against the 38 inches of annual rainfall recorded at Sea-Tac Airport’s weather station, which otherwise saturates flue liners and accelerates freeze-thaw spalling in winter months. Chimney Cap & Crown work is among our most frequent service calls in this city.
Cap Replacement
Signs you need it
You’ll see rust streaks on the chimney face, a cap visibly shifted or tilted from its original position, or water dripping into the firebox during heavy rain.
What it costs in SeaTac
Cap replacement in SeaTac typically runs $180-$340 for standard single-flue galvanized or stainless steel units, with multi-flue custom caps ranging higher.
How we do it
We measure the flue tile or crown opening precisely, fabricate or source the correct cap from our Famco and Copperfield inventory, and secure it with masonry screws and non-corroding fasteners rated for Puget Sound marine exposure.
Crown Repair
Signs you need it
Look for hairline cracks spreading across the crown surface, chunks of concrete missing at the edges, or water pooling on top instead of shedding toward the drip edge.
What it costs in SeaTac
Crown repair in SeaTac generally falls between $450-$780 for crack sealing and resurfacing, while full crown replacement ranges $1,200-$2,400 depending on chimney width and access.
How we do it
We grind out cracked material to sound concrete, apply a bonding agent, and pour new high-psi concrete with a proper drip edge and slope, or apply HeatShield crown coating when the substrate is sound but the surface has failed.
What Chimney Cap & Crown Costs in SeaTac
| Item | Typical range in SeaTac |
|---|---|
| Single-flue cap replacement | $180-$340 |
| Multi-flue cap installation | $380-$650 |
| Crown crack repair/resurfacing | $450-$780 |
| Full crown replacement | $1,200-$2,400 |
| Crown coating (HeatShield) | $650-$1,100 |
How long does a chimney cap last in SeaTac?
Stainless steel caps last 15-25 years in SeaTac’s marine climate, while galvanized steel typically rusts through in 5-8 years due to salt air and persistent moisture; we stock only marine-grade stainless and copper options through our Haven buying network. Call (425) 642-3485 for an exact quote - estimates are free.
Can aircraft vibration really damage my chimney crown?
Yes, we’ve documented accelerated mortar and crown failure in homes directly under SeaTac’s flight path, particularly west of International Boulevard, where cumulative low-frequency vibration loosens cap fasteners and widens existing crown cracks over decades. Call (425) 642-3485 for an exact quote - estimates are free.
Chimney Liner & Rebuild in SeaTac
SeaTac’s original clay tile flue liners, installed in the 1950s-1970s, have reached or exceeded their typical 50-year service life and are now prone to cracking, flaking, and mortar joint failure accelerated by decades of Pacific Northwest thermal cycling. When a Level 2 camera inspection reveals liner damage that compromises safe venting of combustion gases, we specify stainless steel or flexible liner replacement, or partial-to-full rebuild when the masonry shell itself has degraded. Chimney Liner & Rebuild decisions in SeaTac always start with the photo evidence from our camera scan.
Stainless Steel Liner
Signs you need it
Camera inspection reveals cracked or missing clay tile segments, flaking liner walls, or combustible creosote leaking through liner gaps into chimney voids.
What it costs in SeaTac
Stainless steel liner installation in SeaTac typically ranges $2,800-$4,500 for a standard masonry fireplace, with prices varying by flue diameter and story height.
How we do it
We measure the flue precisely, order DuraFlex or Olympia Chimney UL-listed stainless pipe to length, insulate with poured vermiculite or blanket wrap per code, and terminate with a proper top plate and cap.
Partial Rebuild
Signs you need it
The upper chimney above the roofline shows significant spalling, leaning, or mortar loss, while the lower structure and firebox remain sound and properly aligned.
What it costs in SeaTac
Partial rebuilds in SeaTac generally run $3,500-$7,500 depending on height, scaffolding requirements, and whether the crown and flue liner are also replaced.
How we do it
We dismantle the compromised section course by course, salvage reusable brick when possible, rebuild to original dimensions with matching mortar, and install a new crown and cap before final inspection.
What Chimney Liner & Rebuild Costs in SeaTac
| Item | Typical range in SeaTac |
|---|---|
| Stainless steel liner installation | $2,800-$4,500 |
| Flexible liner (offset flues) | $3,200-$5,200 |
| Liner replacement with insulation | $3,500-$5,800 |
| Partial chimney rebuild | $3,500-$7,500 |
| Full chimney rebuild | $8,500-$18,000 |
Does every old SeaTac chimney need a new liner?
No, we replace liners only when camera inspection documents cracks, gaps, or deterioration that creates a fire or carbon monoxide hazard; many clay tile liners in SeaTac remain serviceable with proper sweeping and maintenance. Call (425) 642-3485 for an exact quote - estimates are free.
How long does a stainless steel liner last?
Properly installed 316Ti stainless steel liners carry a lifetime warranty and typically outlast the remaining service life of the masonry chimney itself, even in SeaTac’s wet climate. Call (425) 642-3485 for an exact quote - estimates are free.
